$PEGIFIGATION' forming part of Letters Patent No. 698,564, dated April29, mos. Application filed st temter 4', 1901. Serial No. 74,279. (Nomodel.)

- the county and State of New York, have invented a certain new anduseful Improvement in Ice-Box Covers, of which the following is aspecification.

The invention relates to non-conducting covers for all types ofice-boxes and refrigerators, but is intended more especially for servicein bar ice-boxes, in which the box is a suitably-constructed compartmentformed in the bar or counter. Boxes of this class are usually of sheetmetal and have a large opening at the top, through which the ice isintroduced. This opening is closed by a simple sheet-metal cover and thewhole concealed beneath a removable open-work or perforated metal plateflush with and forming part of the upper surface of the bar or counter.In, this common form of box the upper portion is exposed to the air atthe temperature of the apartment practically without insulation, andconsequently a large proportion of the contained ice meltsuneconomically.

My invention supplies a non-conducting cover for the box and byprotecting the opening therein, which is nearly the whole area of thetop, effects a considerable saving in the amount of ice used. It is alsoinexpensive and neat and attractive in appearance.

The accompanying drawings form a part of this specification and showwhat I consider the best forms of the invention.

Figure 1 is a transverse sectionthrough the upper portion of a bar orcounter having an ice-box equipped with a preferred form of cover. Fig.2 is a transverse section, on a larger scale, of the same cover alone.Fig. 3 is a corresponding top or plan view of a portion of the same.Fig. 4 is a section similar to Fig. 2, but showing a simpler form of theinvention. Figs. 5, 6, and 7 are sections on a still larger scale,showing the construction of three different forms of the invention. Fig.5 corresponds to the form shown in Figs. 1, 2, and 3. Fig. 6 correspondsto the modification shown in Fig. 4, and Fig. 7 shows 'another modifiedform.

Similar letters of reference indicate like parts in all the figureswhere they appear.

A is the upper portion of a bar or counter containing an ice-box A andhaving an opening above the latter closed by the removable perforatedplate A All these parts may be of the ordinary or any approvedconstruction. The box mayinclose coils of pipe (not shown) serving tocool any liquid passing therethrough andhas the usual opening of largearea provided with the surrounding coaming sheet 0, preferably zinc,such as is generally used in the construction of boxes of this class,having a thick sheet D of asbestos applied on the under face and acovering-sheet E of canvas, duck, or other strong woven fabric appliedbelow the asbestos. The sheets of asbestos and canvas are held to themetal by folding over the edges of the latter upon the margins of thecanvas to firmly clasp it and the inclosed asbestos sheet and securelyhold them, and also by rivets F, set at intervals, having large flatheads adjacent to the canvas and slender shanks extending through theasbestos, canvas, and zinc and headed on the upper face of the metal.

The construction of the marginal attachment may be varied. In thepreferred form (shown in Figs. 1, 2, and 5) the sheet metal is bent orfolded around the margins of the canvas, as at O, sufficiently tosecurely engage them andis then bent downward to form a low dependingflange 0 adapted to inclose the lip A on theice-box, and thus be held inplace thereon.

In Fig. 5 I have shown the inner face of the canvas as having beentreated with a suitable waterproofing material, asindicated at G. Suchtreatment may bedesirable in some situations,but will not be generallynecessary.

In the form shown in Figs. 4 and 6 the sheet metal is simply folded downat 0 upon the margins of the asbestos and canvas sheets and the flange Cof the above-described form is omitted. This simple form of theinvention by reason of avoiding the necessity for closely matching tothe contour of the lip A is much less expensive to manufacture.

Fig. 7 shows a form in which the asbestos and canvas sheets are bentdownwardly at the margin with the metal sheet to form a composite flange0*, reinforced on its inner face where it contacts with the lip A" bythe upward extension of the sheet metal at 0 This construction has theadditional feature of protecting the lip A with a non-conducting flange,as well as covering the ice box opening.

The rivets F serve in holding the asbestos and canvas from sagging awayfrom the metal and becoming torn or defaced by contact with the ice orarticles in the box.

The sheet metal supplies the required rigidity, the asbestos servesefficiently in preventing the transmission of heat to the ice, and thecanvas offers a clean protective covering to the soft absorbentasbestos. The canvas or duck is peculiarly well adapted to withstand thewear to which the cover is subjected and by its porous or open characterallows any moisture or odors absorbed by the asbestos to escape freelywhen the cover is reversed and exposed to the action of the air andsunlight.

The rivets F may be omitted in small covers, and the thickness of theasbestos sheet may be varied, or this portion may be built up of severalthin sheets.

Other strong fabric than canvas or duck may be used for thecovering-sheet, if preferred, and the sheet forming the body, describedas zinc, may be of other metal. Y

The cover may be applied in other forms of refrigerators than the barice box shown, and the proportions may be varied to suit therequirements of the various situations in which the cover may beemployed.

I claim- 1. The ice-box cover described, comprising a sheet of metalforming the body, a sheet of asbestos on the under face thereof, and acovering-sheet of woven fabric applied on the under face of saidasbestos sheet, the latter and said fabric held in position by foldingthe edges of the metal upon them and securely clamping both, allcombined substantially as specified.

2. The ice-box cover described, comprising a sheet of metal forming thebody, a sheet of asbestos on the under face thereof, and acovering-sheet of woven fabric applied on the under face of saidasbestos sheet, the latter and said fabric held in position by foldingthe edges of the metal upon them and securely clamping both, and rivetsextending through said fabric, asbestos, and metal to hold said fabricand asbestos sheets closely adjacent to said metal sheet throughout thewhole area, all combined substantially as specified.

3. .The metal sheet C, asbestos sheet D, and fabric sheet E superposedupon each other, the fold 0 along the margins of said metal sheet,serving to hold the edges of said asbestos and fabric sheets, and theflange 0 formed by bending downward the edges of said metal sheet, allcombined and arranged to serve with abar ice-box,substantiallyas hereinspecified.

4-. The metal sheet C, asbestos sheet D, and fabric sheet E superposedupon each other, the fold 0 along the margins of said metal sheet,serving to hold the edges of said asbestos and fabric sheets, the flange0 formed by bending downward the edges of said metal sheet, and therivets F serving to hold said asbestos and fabric sheets to said metalsheet throughout the whole area, all combined and arranged to serve witha bar ice-box, substantially as herein specified.

In testimony that I claim the invention above set forth I affix mysignature in presence of two witnesses.
